Primary Outcome Measures:

Number of Participants With Increased Bone Mineral Density [ Time Frame: at 12 months ] [ Designated as safety issue: No ]
Number of participants with increase in bone mineral density at Lumbar Spine and/or Hip at 12 months as compared to the bone mineral density at Lumbar Spine and/or Hip obtained before therapy (baseline values)

Secondary Outcome Measures:

Participants (1) With Fractures Before and After Therapy,(2)Analysed for Average Changes From High to Near Normal Mineral Apposition Rate (MAR) After Therapy,(3)Analysed for Average Insignificant Changes in Biochemical Markers After Therapy. [ Time Frame: Before and 12 months after treatment with alendronate ] [ Designated as safety issue: Yes ]
Participants (pts) with fractures bef.and aft.therapy; pts analysed for average changes in mineral apposition rate (MAR) (high (1.9um/day) to near normal (1.2 um/day)as revealed in bone biopsies. MAR is the distance between the two tetracycline labels (um/day). The data represent the average of 10-17 measurements of the disltance obtained by reading 2-7 individual slides of bone biopsy and pts analysed for average insignificant biochemical markers (serum bone specific alkaline phosphatase for bone formation and urinary N-telopeptide for resorption)to determine the effect of therapy.

Arms	Assigned Interventions
Experimental: 1 Alendronate for 12 months Ten children will take alendronate 35mg or 70mg weekly depending upon the body weight for 12 months. Patients will also take calcium supplement daily.	Drug: Alendronate Pill, 35mg or 70mg weekly, depending upon the body weight for 12 months. Other Name: Fosamax

Detailed Description:

PROTOCOL OUTLINE:

Patients receive oral alendronate sodium weekly for 1 year. Treatment continues in the absence of disease progression or unacceptable toxicity.
